I don't know if this was already documented, but in addition to using Command-click on the Safari window title to show the nested directories for a web site, Safari 4 lets you do it with a right-click (or Control-click) of the mouse as well.

[robg adds: I was positive we had this documented here, but I can't find it while searching now. If it's been posted before, please let me know.]

What's especially cool about this hint, and is not really noted in the article, is that you can also, like in Finder, use the popup menu to navigate the current hierarchy. This is super useful when your standard History pulldown either the Menubar or the Back button) shows ten or twenty of the same page titles (e.g. "MyWebStore Checkout Process" or "Library of Downloads for MyCompany").

This tool breaks, however, if the root URL changes (e.g.: www.macosxhints.com -> macosxhints.com or -> forums.macosxhints.com).

Thanks for posting this; it used to work in older browsers dating back to Navigator, and whenever it stopped (or never started?) working properly in Safari, I stopped using it day to day.

I'm glad to be reminded of this today, as I search for things related to Command-click in Safari. In Safari 4 beta, along with experimentation with tabs on top, came a subtle change to this that makes it more logically consistent, but less convenient for me: Now holding the Command key as you choose another directory in the hierarchy loads that page in a new tab (more precisely, it follows whatever way you have Prefs > Tabs set). In order to load a higher-up page without making a new tab, I learned to release the Command key before the mouse button. But this right-click (or, for me, double-tap on my trackpad) is better all around.
